After Root Canal Therapy — Post-Operative Instructions
What Is Root Canal Therapy?
Root canal therapy is an endodontic procedure that removes infected or damaged tissue (the “pulp”) from inside your tooth. After the canals are cleaned and shaped, they are filled and sealed to prevent future infection.
This treatment saves the natural tooth and relieves pain. A temporary filling has been placed today to protect the tooth until your permanent crown is ready. Following these care instructions — especially the crown timeline — is critical for long-term success.
Your After-Care Instructions
Immediately After Your Appointment
The first 30 minutes are critical for your temporary filling
First 30 Minutes
Do not eat or drink. Your temporary filling needs ~30 min to fully harden.
If Numb
Do not chew until numbness has completely worn off.
ALSO
Chewing & Eating Guidelines
Protect the weakened tooth until your crown is placed
Critical
Do NOT chew on the treated tooth until the permanent crown or filling is placed.
- Ice, hard candy, nuts, and pretzels — these can fracture the weakened tooth
- Sticky foods such as gum and caramels — these can pull on the temporary filling
- Chew on the opposite side of your mouth until your permanent crown is placed
Temporary Filling Care
What's normal and what needs attention
Normal
The temporary filling may wear down or "divot" slightly with use over time.
Call Us
It is uncommon for the filling to fall out completely. If this happens, contact our office.
If Filling Comes Out After Hours
Place a small amount of over-the-counter temporary dental filling material (available at most pharmacies) until you can be seen.
